       revision 1.7.1.4
       date: 90/04/13 12:43:56;  author: ram;  state: Exp;  lines added/del: 196/115
       Changed DEFINE-STORAGE-CLASS to give each SC a self-load cost of 0.  Fixed
       it to set *META-SC-NUMBERS* at load time as well as at compile time.
       Souped up DEFINE-MOVE-VOP to implicitly define moves for all SC pairs
       that can be moved with use of load functions.
       Added support for the new :MOVE-ARGS option.
       Fixed up load function computation a bit.  Folded the SCs which share a
       load function together.
       Added backward compatibility for the old :SCS and :TYPE options to
       the :TEMPORARY option.
       Fixed arg restriction computation.
       Fixed DO-ENVIRONMENT-IR2-BLOCKS and DO-LIVE-TNs.

       revision 1.7.1.3
       date: 90/04/02 15:24:52;  author: ram;  state: Exp;  lines added/del: 29/17
       Frobbed the syntax to DEFINE-MOVE-FUNCTION to indent better.
       Changed DO-LIVE-TNS to iterate over :MORE TNs properly, rather than
       ignoring them.  We need this now that DO-LIVE-TNS is used in
       INIT-LIVE-TNS.

       revision 1.7.1.2
       date: 90/03/27 13:01:07;  author: ram;  state: Exp;  lines added/del: 453/218
       Big changes for new non-descriptor support.
      
       New DEFINE-STORAGE-CLASS options: :SAVE-P, :ALTERNATE-SCS, :CONSTANT-SCS.
       SB name NUMBER-STACK has magic significance.
      
       New interfaces DEFINE-MOVE-FUNCTION and DEFINE-MOVE-VOP.
      
       Flushed PRIMITIVE-SUBTYPEP, PRIMITIVE-TYPE-UNION.
      
       Flushed :MOVE, :COERCE-TO-T and :COERCE-FROM-T options to PRIMITIVE-TYPE-VOP.
       (only :CHECK remains.)
      
       Flushed DEFINE-MOVE-COSTS and DEFINE-SAVE-SCS.
      
       Flushed support for temps restricted to multiple SCs temporary primitive types.
       :SCS is flushed in favor of :SC.  Flushed support for NORMAL temps (i.e. not
       either wired or restricted.)  :SC is now required for temps.
      
       Moved operand loading back inside the generator function, and allow loading
       to be conditionalized by the :LOAD-IF option.  Allow the load-TN to be accessed
       with the :LOAD-TN option.
      
       Allow :FROM (:TO) to be specified in results (arguments).
      
       Dump load-scs vectors instead of restriction bit-vectors.  This contains the
       additional info of what SCs can be loaded by load function and what SC to
       load into.
      
       Compute operand costs from the load-function costs + the costs for any
       move/coerce VOPs applicable.
      
       Added support for the new :OR and :CONSTANT operand restrictions.
      
       Allow :NOTE to be NIL (meaning don't give efficiency note, overriding any
       inherited note.)
       ----------------------------
       revision 1.7.1.1
       date: 90/03/06 11:08:02;  author: ram;  state: Exp;  lines added/del: 71/117
       Start hacking on improved support for non-descriptor values.
